To all whom it may concern: 7

- Be it known that I, EBBERT J. LUND, a

citizen of the United States, residing at Jamestown, county of Chautauqua, and State of New York, have invented new and useful Improvements in Metallic /Vindow: or Screen Frames, of which the following,

taken-in connection with the accompanylng drawings, is a specification.

The invention relates to improvements in sheet metal window and screen frame; and the object of my improvement is to provide a sheet metal frame construction which is adapted to hold screen fabric between parallel angular plates or surfaces and also to resiliently hold window glass in the angle of one of said parallel plates acting as a stop for said glass, and to soconstruct the tubular sheet metal frame sides that great rigidity or stiffness is given to the entire frameyand the invention consists in the construction and arrangement of the parts, as shown in this specification and the ac-. companying drawings and pointed out in the claims. a i

- In the drawings Figurell is an elevation 'of' a window having a sheet metal frame. Fig. 2 1s a crosswise sectional view of the frame at llIIe X in F 1g. 1, filled with screen fabric. Fig. 3 is a lengthwise sectional viewof the frame at line Y Y in Fig. 1 filled with window glass. Fig. 4 is a perspective view of a portion of the top or bottom rail with a" portion of screen fabric therein. Fig. 5 is a perspective view of a top or bottom corner of the frame showing the top 'orbottom rail in section and the under side of the bottom rail or the upper side of the top rail according to whichever corner is chosen. Fig. 6

' is a detail perspective viewfof the parts forming one of the lateral sides of-the frame and showing the angular form of the edge of the screen fabric in order to hold the same. Fig. 7 is a detail perspective view of one of the locking strips for the window glass or screen fabric; and Fig. 8 is a similar view of the other locking strip.

Like numerals of reference refer to corresponding parts in the several views.

The numeral 10 designates the window glass and the numeral 11 the screenfabric.

The frame for holding the screen fabric or glass is formed of sheet metal with the lateral side pieces 12 and end pieces 13 united preferably with miter joints at the Specificationof Letters Patent.

The'lateral' tubular frame sides 12 are. formed on their inner edges with the central lengthwise'inwardly extending lip 15 which 0. supports one side of a filler of glass 10 or wlre fabric 11 with its flat face 16. A

lengthwise angle 17 is provided along the inner edge of the fiat face 16. against which the screen fabric 11 draws. A lengthwise groove or pocket 18 isfprovided parallel to angle 17 and the sheetmetalthen extends across to the opposite side of the frame sides 12 or 13 and isthere given a return bend 19 which provides a groove 20- beneath the same 1 The locking strips 21 and 22 are;pro vided for the glass or screen fabric within the grooved inner edge of'the frame sides. The strip 21 is provided with a straight face 23 opposite face 16, an angle24 correspondlng to angle 17, and? an edge 25 which'flocks within, groove 18.; The outer edge (if-strip 21 is given a return bend 26 on its outer.

locks. The strip 22 slidably engages be-J neath return bend 26 and return bend 19:- or may be inserted beneathone of said is turn bends and sprung beneath the other and is so shaped as to brace strip 21Ifirmly yet resiliently against the glass 10 or screen fabric 11 and lip 15, as said strip 22 braces between the locking flanges 19 and 26. The strips 21 and 22 thus fo-rm'a lip for the other side of the glass or screen from lip 15.

The lateral edges of the frame sides 12 are formed in a groove 28 to'slidably engage a guide strip on the window casing by being bent inward at 29 at eacli side. The edges of the sheet metal are LlIlltGClftO a lengthwise strip 30 within sides 29 by means of return bend joints 31 which are formed close to the walls 29 and extend out crosswise between the two walls, thereby fitting strip. 30 closely within said walls 29. When the joints 31 are firmly pressed together, the strip 30 forms a bottom for the groove 28and at the 13 are formed exactly similar to the lateral sides 12 except that the upper and lower edges of the rails 13 must be flat and not grooved. Therefore, in order to obtain the same rigidity of construction -which the strip 80 gives to the frame 'side 12, the top or bottom of rails 13 have the inturned bends 29 and the strip 30 continued across the same to the groove 28 at each side of the frame, except that they are only given a sufficient depth to allow for the thickness of strip 80, so that after the return bend j oints 31 are formed on the strips 30 for the top and bottom rails the upper and lower edges of said rails will be fiat. The slight crease made by the joints between the strip 30 and the walls 29 is easily filled by the enamel in finishing the screen frame.

I It is obvious that a frame made as herein described permits of the insertion of the screen wire between the correspondingly bent faces or plates formed by the faces 16 and 23 and angles 17 and 24-, and that said angles in said plates will hold the screen wire rigidly so that it can not be withdrawn from the frame by blows 'upon the screen wire after insertion in the frame also that the strips 21 and 22 may be slipped or sprung into place alongside the screen fabric and that strip 22 may be made of such a width as to brace strip 21 with its face 23 firmly against the screen fabric; also that said strips may be easily removed for the renewal of the screen fabric; also that strip 21 maybe moved with its face 23 a sufficient distance from the face 16 to permit of the insertion of the edge of window glass with any necessary cushions or fastening material therebetween, and that the angle 21 in strip 21 will form an inward limit for the movement of the edge of the glass; also that the strips 21 and 22 will form a resilient holding means for the glass which is so necessary in sheet metal construction, the spring of the sheet metal giving the resiliency required, the width ofthe strip also being proportioned to the thickness of the glass.

I claim as new 1. In a window or screen frame,-

hollow frame having spaced sides formed of sheet metal one of the sides having a wall against which one side of the screen fabric or glass filler abuts and also having a pocket of U- shape off set from the wall and located in spaced relation to the side walls of the frame, a strip having a wall which is located opposite to the first named wall and an an gular wall against which the filler engages and having a part which projects into the pocket, a second strip between the free side of the first strip andthe adjacent frame side,

and interlocking connections between said' second strip, said adjacent frame side and the first named strip.

2. In a window or screen frame, a sheet metal frame having tubular sides, the sheet metal bent to form molding along the inner edge of said frame 'sidefs, said molding having a flat inner face for holding one side of the screen fabric or glass, the sheet metal of said fiat face turned at an angle and continued in an inner recess, a sheet metal binding strip bent at a similar angle to said angle in the fiat inner face of said molding and holding within said recess, said binding strip facing the opposite side of the screen fabric or glass from said flat inner face of said molding, said binding strip having a return bend flange on its edge, a second binding strip, holding means on the edge of said tubular frame for one edge of said second binding strip and the other edge of said second binding strip sprung beneath said return bend flange on the first binding strip to hold the glass or screen fabric.

3. In a window or screen frame, sides formed of sheet metal having a wall against which one side. of the screen fabric or glass abuts and further having a pair of spaced walls located beyond the inner side of the first named wall, one of the frame sides having an inwardly extending fiange located on one side of the pair of spaced walls, a strip of metal having an off-set side which operates with the inner wall of said pair of walls to hold the fabric or glass in position and having a wall which extends opposite and in spaced relation to the first named wall, said strip having an out-turned flange at its opposite side, and a second strip having one side engaged with said out-turned flange of the first named strip and having its opposite side engaged beneath the inwardly extending flange of the frame side.

In testimony whereof I have signed my name to this specification in the presence of two siibscribing witnesses.
